When using virtual desktop software like VirtuaWin, desktop switching can cause dialogs of memoQ to close without warning. Fortunately, there is a workaround for recent versions of VirtuaWin.
- Open the file tricky.cfg contained in the VirtuaWin settings folder: [user profile]\Application Data\VirtuaWin.
- Add this line: cr:WindowsForms10.*
- Restart VirtuaWin.
This will cause VirtuaWin to handle memoQ dialogs differently, avoiding the problem of abruptly closed dialogs. It is not yet known whether similar fixes are possible for other virtual desktop managers like Microsoft Virtual Desktop Manager.
